To all whom it may concern: I

Be it known that l[, JAMES D. TIPPLE, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented new and useful Improvements in Furnace Fire-Pots, of whichthe following is a specifications This invention relates to improvementsin furnace fire pots and especially with reference to improvements inthe construction of fire pots especially used in hot air furnaces,theobject of the invention being to provide a fire pot with liners whichare detachable therefrom and which coact therewith to form air spacesbetween the liners and the fire pot to prevent the fire pot from beingburned out and to also promote draft in the fire pot, the inventionconsisting in the construction, combination and arrange ment of deviceshereinafter described and claimed. I

in the accompanying drawing :Figure 1 is a perspective view of a firepot constructed in accordance with my invention with some of the linersremoved. Fig. 9 is a vertical sectional viewoi the same. Fig. 3 is adetail front elevation of one'of the liners.

in accordance with my invention the fire pot 1 which may be of anysuitable size and shape is provided at its upper end with an inwardlyextending annular flange 2 and is also provided on its inner side withan annular inwardly extending flange 3 which is spaced somewhat belowthe flange 2, so that an opening 4: is formed between said flanges. thatof the flange 3 and the latter is overhung by the former. The upper sideof the flange 3 is beveled or inclined downwardly and outwardly as at 5.

in combination with the fire pot I pro-,

vide a series of detachable liners 6 which are segmental in form and arehere shown as having parallel side edges 7. Each liner is beveled on itsfront side at its upper end as at 8, the said bevel corresponding withthe beveled face 9 of thefire pot flange 2. Each liner also has at itsupper end on its outer side a supporting flange 10 which is inclineddownwardly and outwardly and is adapted to be placed in the groove oropening 4 between the flanges 2 and 3 of the fire pot and the rest onthe upper side of the The width of the flange? exceeds flange 3 so as tosupport and suspend the liner. Each liner is also provided near itslower end on its rear side with spacing lugs 11, two or more, to bearagainst the inner side of the fire pot and space the liner from the wallof the fire pot, the flange 3 of the fire pot also serving to space theliner from the fire pot so that an air space 12 is formed around thefire pot, on its inner side and between the fire pot and the liners.Each liner also has a suitable number of air openings 13 some of whichare arranged centrally in the liners and others being space between thefire pot and the liners not only serves to protect the fire pot butalso, in connection with the air openin s in the liners, serves togreatly promote t e draft 7 through the fuel in the fire pot. Theoverhanging flange 2 of the fire pot wall covers I and protects theupper ends of the liners andthe coacting inclined upper surfaces'of thesupporting flange 3 and the supporting lugs 10 of the liners causes theliners to remain in place and their own weight prevents them from movingcaus ually inward and from becoming casually displaced.

Having thus described my invention, it claim p The herein described firepot having an inwardly extending supporting flange on its inner side andalso having a fixed overlapping flange spaced above, wider than andoverhanging said supporting flange, said supporting flange having aninclined upper side, in combination with a series of liners each havinga supporting flange on its outer side at its upper end arranged in thespace between the flanges of the fire pot, said supporting flangeserving to suspend said lining member and each of said lining membersfitting closely against the underside of the upper flange of the firepot'and having its upper end protected thereby from the effects of heatand escape of ashes, the said liners also having outwardly projectingspacing lugs In testimony whereof I afiix my signature gear their lowerends bearing against the in presence of two Witnesses.-

re pot so that said liners are spaced by i said lugs and said supportingflanges from I JAMES TIPPLD' the fire pot, said liners being alsoprovided Witnesses: with. air openings communicating with the W. B.BALLARD,

' space between them and the fire pot. B. S. SNELL. v
